Thermosensation01:43

Thermosensation

32.3K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

Diversity of Archaea III

109
Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...

Hyperthermophilic Bacteria

142
Domain Bacteria includes some unique hyperthermophilic species. They exhibit remarkable adaptations that enable survival in extreme environments.Thermotoga species are rod-shaped, gram-negative, non-sporulating hyperthermophiles that form a sheath-like envelope called a toga. They ferment sugars or starch, producing lactate, acetate, CO₂, and H₂, and can also grow via anaerobic respiration using H₂ and ferric iron. Found in hot springs and hydrothermal vents, over 20% of their...

Olfaction01:25

Olfaction

45.8K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Summary

Deep-sea shrimp use temperature, not smell, to find hydrothermal vents. While they groom their antennae, bacterial biofilms hinder olfactory detection, making temperature the primary orientation cue.

Area of Science:

  • Marine Biology
  • Deep-sea Ecology
  • Sensory Biology

Background:

  • Deep-sea vent species, like hydrothermal shrimp, navigate lightless environments.
  • Olfaction and temperature detection are potential sensory modalities for locating active hydrothermal vents.
  • Understanding sensory abilities is crucial for deep-sea species survival and orientation.

Purpose of the Study:

  • To investigate the olfactory capacities of hydrothermal shrimp, specifically *Rimicaris exoculata* and *Mirocaris fortunata*.
  • To assess shrimp grooming behavior and attraction to environmental cues like food odors and vent fluid markers.
  • To compare the sensory behaviors of vent shrimp with coastal species (*Palaemon elegans*, *Palaemon serratus*).

Main Methods:

  • Experiments were conducted under both deep-sea and atmospheric pressure conditions.
  • Observed grooming behavior of sensory appendages in vent and coastal shrimp species.
  • Assessed behavioral responses to olfactory stimuli (food odors, fluid markers) and temperature gradients.

Main Results:

  • Hydrothermal shrimp exhibit grooming behaviors typical of crustaceans, but bacterial biofilms impede olfactory structure cleanliness.
  • Despite possessing functional sensory structures, vent shrimp did not show significant attraction to tested olfactory cues.
  • Temperature was identified as a clear attractant, confirming its role as a key orientation signal for vent shrimp.

Conclusions:

  • Temperature, not olfaction, is the primary cue for hydrothermal shrimp navigating to vent sites.
  • Bacterial biofilms on sensory appendages may limit the effectiveness of olfaction in these species.
  • This study highlights the critical role of thermal sensing in the survival strategies of deep-sea vent fauna.
